Evaluation of the Strontium Isotope Ratios in Soil–Plant–Fruit: A Comprehensive Study on Vignola Cherry (Ciliegia di Vignola PGI) [PDF]
FoodsThis study investigates the potential of strontium isotopes as a geographical tracer for Vignola cherries. Despite several studies having employed this indicator to trace the origin of food products, the mechanisms underlying the fractionation and ...

Coupled strontium-calcium isotopes in Archean anorthosites reveal a late start for mantle depletion [PDF]
Nature CommunicationsVoluminous felsic continental crust is, as far as we know, unique to Earth, yet the timescales of its earliest growth remain debated. Archean mantle evolution is complementary to crustal growth but is largely unconstrained for strontium isotopes due ...

Understanding intra-individual isotopic variability in modern cremated human remains for forensic and archaeological studies. [PDF]
PLoS ONECremated bone fragments can be studied using structural, elemental, and isotope analyses in archaeological contexts to reconstruct funerary practices and understand past mobility and migrations of populations that practiced cremation.

Strontium isotope effect on Solid-Liquid extraction system using a polymer resin with 2.2.2-Cryptand anchor groups [PDF]
مجله علوم و فنون هستهای, 2020 The chemical isotope exchange with macrocyclic polyethers is one of the relatively new methods for isotope separation. These separations are based on the phenomenon of isotope effect, in which the kinetic and the stability of the complex formation ...
